Is it possible to block Snapchat on the Sophos XG 85?

Question

Looking to install a Sophos XG 85 for a small 4user network. 
 Does anyone know if it's possible to block chat programs Snapchat on the XG 85 model? Or do I need to look at a stronger unit?

Seems XG85 would be good enough for 4 user network and using only Web and Network Protection features.

This could work, never tried it but the point is, you would have to decrypt this traffic.

 Maybe this is not possible on Mobile Devices and so to speak, the Snapchat will still be able to communicate through XG (encrypted in HTTPS). 
 
 Another point is... The user will still be able to simply switch to Mobile and still use Snapchat. 
 I guess, you should think about Sophos Mobile to restrict this on Mobile level.
